Information about the Datasets Used with OdontoSearch 3.2
The three distinct datasets utilized as the core of OdontoSearch correspond to different U.S. populations, one composed of a military population and two derived from the civilian population. The datasets are referred to as: TSCOHS (Military), BigMouth (Civilian), and NHANES (Civilian). The data from these studies have been pooled together for use with OdontoSearch 3.2. All datasets are composed of anonymized dental records of United States residents over the age of 14. In total, the OdontoSearch 3.2 dataset consists of 107,002 individuals.
Customized searches can be completed based on age, sex, and ancestry. Ancestry data were not specified for some of the records in the BigMouth dataset, but age and sex are available for almost every record within the OdontoSearch program. Users have to ability to query individual datasets or to pool all of the records.
TSCOHS Data (Military):
The dental health data representing the military population was graciously provided by the Tri-Service Center for Oral Health Studies, which is affiliated with the Uniform Services University of the Health Sciences, Bethesda, Maryland. The raw data from this source were part of an ongoing study observing dental health throughout the active duty and recruit population of the U.S. military. The data were collected in 1994 and 2000 as part of two phases of the Tri-Service Comprehensive Oral Health Survey (TSCOHS). The 1994 data are composed of detailed dental conditions of active duty and recruits from all branches of the service and from different military installations across the continental U.S. The year 2000 phase of TSCOHS considered all branches of the military, but only in regard to recruits. Because the 2000 data only included recruits, the combined TSCOHS dataset is biased towards the recruit population as opposed to active duty. Individuals in the study ranged from 17-69 years of age. Additional information regarding TSCOHS can be found at their website (http://www.usuhs.mil/tscohs).

BigMouth Data (Civilian):
The dental health data representing a major portion of the OdontoSearch reference population was graciously provided by the BigMouth Dental Data Repository. BigMouth is composed of electronic health records contributed by numerous US dental schools that are part of the Consortium for Oral Health Research and Informatics (COHRI) for research purposes (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4215035/). The total BigMouth database holds dental information on over 2 million patients, a subset of which has been incorporated into OdontoSearch. As the BigMouth dataset contains information on a range of individuals from infants to the elderly, a subset of de-identified data was extracted for OdontoSearch that consists of individuals from 14-90 years of age.

NHANES Data (Civilian):
The National Health and Nutrition Examination Survey (NHANES) dental data are periodically collected as part of an initiative by the Centers for Disease Control and Prevention to study dental health. Participants in the various NHANES studies represent a cross-section of the US civilian population. Dental data from several NHANES studies were consolidated covering the years from 1988 through 2014. The NHANES study is a multifaceted health examination survey that was conducted in various locations across the United States to collect data on the civilian, non-institutionalized population. Dental health information represents only a single facet of the overall study. For adults, only data for 28 permanent teeth were collected (3rd molars excluded). These data are available to the general public for research purposes via their website (http://www.cdc.gov/nchs/about/major/nhanes/datalink.htm). As the NHANES dataset contains information on a range of individuals from infants to the elderly, a subset of data was extracted for OdontoSearch that consists of individuals from 14-90 years of age

Combined Civilian Data (BigMouth and NHANES)
The dental health data representing a combination of private (BigMouth) and public (NHANES) civilian dental data that consists of individuals from 14-90 years of age. See the corresponding sections for information related to these samples.

Combined Data (TSCOHS, BigMouth and NHANES):
This dataset is simply a compilation of all of the data from the TSCOHS, BigMouth and the NHANES data. See the corresponding sections for information related to these samples. As this dataset represents a large sample of the contemporary U.S. military and civilian population, it should be very useful for calculating frequency values related to modern forensic cases. The combined data format includes a total sample size of 107,002 individuals.
